End-group modification of polymer and oligomer structures is a powerful tool for a diverse range of applications. Living ROMP polymerizations are well-suited for this type of precise end-group manipulation, but the strategy for functionalization must be chosen carefully based on metathesis catalyst, polymerization conditions, and other application-specific limitations. This excellent review article from the Kilbinger group provides a comprehensive “field guide” to the common strategies and challenges for this type of precision end-group functionalization, providing an excellent survey of recent work with ROMP catalysts of all types.
Strategies for end-group modification of ROMP polymers at various polymerization stages
While outlining strategies for incorporation of functional endgroups at different phases of polymerization, Kilbinger and Hilf succinctly present the pros and cons of various methods. Their “field guide” is particularly impressive, tabulating functional groups, catalyst types, and details of the polymerization and functionalization efficiencies in one easy-to-understand table. As wide-ranging applications move toward functionalized ROMP structures to meet their needs, this review is likely to become a highly cited source.
